Environmental issues in Bulgaria
Air pollution from industrial emissions; rivers polluted from raw sewage, heavy metals, detergents; deforestation; forest damage from air pollution and resulting acid rain; soil contamination from heavy metals from metallurgical plants and industrial wastes.
Over the last 6-7 years there have been unprecedented floods in Bulgaria. Average summer temperatures have risen considerably. There is evidence of a trend towards desertification and pressure on water resources, especially in southern regions of the country, along with signs of gradual northward migration of various plant and animal species.
Bulgarian scientists at the Bulgarian Academy of Sciences anticipate the spread of desertification, with the climate in Bulgaria becoming sub-tropical by the period from 2050 to 2080. A number of traditionally cultivated crops are expected to become unviable and expectations include the growth and spread of pest and disease species hitherto unseen in Bulgaria and resilient to the new climatic conditions.
